Cooler Units - products

Variants of Cooler Units

Our fixed installations use any combination of 3 cooler: a downwards, sideways and top discharge unit.

Which unit we choose will dependend entirely on location and will be affected, for example by:

• Wanting to avoid roof penetration
• Amount of ductwork implied by location
• Ease of access to installation & maintenance.

Pre-coolers

Cooler units can be supplied without the fan as a "wet box" to act as a pre-cooler for an existing system or in instances where a higher duty fan is required. Air flow resistance in this configuration is low: for example a down-discharge unit has a resistance of 50 Pa at 14,000m³/hr.
